Quizplus · Accepted Answer

The submucosa layer of the digestive tract contains a dense irregular connective tissue called the submucosal plexus or Meissner's Plexus. This layer is located between the mucosa and the circular smooth muscle layer of the muscularis externa. It contains blood vessels, lymphatic vessels, and nerves that supply the mucosa and submucosa. The muscularis mucosae is a thin layer of smooth muscle that separates the lamina propria from the submucosa. It is responsible for moving the mucosa in a rhythmic pattern. The lamina propria is a loose connective tissue layer that lies beneath the epithelium and is part of the mucosa.
